Abstract: A process for producing isotropic and mesophase pitch with reduced solids contamination from aromatic liquids contaminated with solids, such as catalyst fines or semi-coke. Contaminated feed is charged through one or more pitch forming reactors which discharge a pitch rich liquid and a vapor phase with reduced solids contamination. The vapor phase is cooled, condensed and may be charged continuously to another pitch forming reactor in parallel or used intermittently as a total or partial replacement for solids contaminated feed.

Abstract: A process for making mesophase and/or isotropic pitch. An aromatic rich liquid is charged at high temperature and pressure to a first thermal polymerization reactor to produce an effluent stream which is flashed to remove unconverted or partially converted feed as a vapor yielding a liquid phase enriched in isotropic pitch. The enriched isotropic pitch liquid is charged to a second thermal reactor and reactor effluent flashed to produce mesophase pitch and a vapor phase. The vapor phases from both flashing steps are condensed and combined for recycle of a liquid aromatic rich stream to the first reactor. Flashing from the first reactor cools the liquid phase which is enriched in isotropic pitch. This enriched stream is mixed with a superheated fluid, preferably steam, upstream of the second reactor.

Abstract: Producing mesophase pitch from liquid hydrocarbon feed comprising multi-ring aromatic compounds. In a first stage reactor feed is converted to isotropic pitch product contaminated with mesophase pitch. Contaminated isotropic pitch is charged to a second stage reactor where mesophase formation by self-assembly into spherical crystal clusters produces a mesophase pitch product. Water or steam added to the first stage reactor increases conversion of aromatic liquid feed, increases mesophase contamination of isotropic pitch product and reduces coke formation in the isotropic pitch reactor.

Abstract: A process for making mesophase and/or isotropic pitch. An aromatic rich liquid is charged at high temperature and pressure to a first thermal polymerization reactor to produce an isotropic pitch rich liquid which is flashed. Residual liquid is charged to a second thermal reactor to produce mesophase pitch. The reactors can be either tubular reactors or CSTRs.

Abstract: A method for producing pitch can include: hydroprocessing a challenged feed from a refinery operation to produce a hydroprocessed product; distilling the hydroprocessed product to yield one or more upgraded fractions and a resid fraction; and solvent deasphalting the resid fraction to yield a deasphalted oil stream and a hydroprocessed pitch stream. The resultant pitch can have a micro carbon residue (MCR) of 50 wt % or greater, a solubility in toluene of 95 wt % or greater, and a softening point of 200° C. or less. The pitch can optionally be fluxed with a fluxing solvent.
